Follow your "gut"-calling for colonoscopy in patients with upper gastrointestinal adenomas: a systematic review and meta-analysis.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Background: Early detection and removal of adenomas through colonoscopy significantly reduces colorectal cancer (CRC) incidence and mortality. However, there is a lack of summarized evidence evaluating the necessity of colonoscopy in patients with upper gastrointestinal (UGI) adenomas. Objectives: We aimed to assess the risk of colorectal neoplasms in individuals with UGI adenomas to provide evidence on whether patients with UGI adenomas should undergo colonoscopy examination. Design: Systematic review and meta-analysis. Data sources and methods: A search of PubMed and Embase was performed up to November 30, 2024. The studies comparing the risk of colorectal neoplasms in patients with and without UGI adenomas were included. Pooled odds ratios (ORs) of colorectal adenomas were estimated using random-effects models. Trial sequential analysis (TSA) was performed to control for random errors. Results: A total of 15 studies with 210,508 participants were included. Our analysis revealed a significant association between UGI adenomas and an increased risk of colorectal adenomas (pooled OR 2.36, 95% confidence interval (CI), 1.82-3.06). TSA confirmed the reliability of these findings. In addition, the presence of duodenal adenomas was linked to an increased risk of advanced colorectal adenomas (pooled OR 2.95, 95% CI, 1.80-4.84) and CRC (pooled OR 2.15, 95% CI, 1.51-3.06). Sensitivity analyses supported the robustness of these associations. Subgroup analysis suggested that patients with either gastric or duodenal adenomas had a higher risk of colorectal adenomas. Conclusion: This is the first meta-analysis suggesting that patients with UGI adenomas are at increased risk of colorectal adenomas and CRC. These findings highlight the need for colonoscopy in this patient population and supplement colonoscopy screening guidelines.
